FAQ

What is a high availability server?

A high availability server is a part of a hosting infrastructure designed to ensure that a website or application remains operational with minimal downtime. These servers utilize redundant components, automatic failover mechanisms, and load balancing to maintain consistent performance and availability, even in the event of hardware failures, maintenance, or unexpected traffic spikes.

What is the difference between HA (High Availability) and cluster?

High Availability (HA) and clustering are related concepts, but they serve different purposes:

- High Availability (HA) is a hosting approach focused on minimizing downtime and ensuring the continuous operation of a website or application. HA systems use redundant components, automated failover, and other techniques to maintain availability in case of server failures or maintenance.
- Clustering, on the other hand, involves connecting multiple servers to work together as a single unit. Clusters can improve performance, scalability, and redundancy by distributing workload and resources among the connected servers. While clustering can contribute to high availability, its primary goal is to boost performance and ensure the efficient use of resources.

What is the difference between HA (High Availability) and failover?

High Availability (HA) and failover are two techniques used to maintain the uptime and reliability of a hosting environment. However, they differ in scope and implementation:

- High Availability (HA) is a broader approach that encompasses various strategies, including failover, to minimize downtime and ensure continuous operation. HA systems often use redundant components, load balancing, and other techniques to maintain service availability.
- Failover, on the other hand, is a specific mechanism used within HA systems to handle server failures or maintenance. In case of a server failure, failover automatically redirects traffic to a backup server, allowing the website or application to continue functioning with minimal disruption.

What are the advantages of High Availability (HA)?

High Availability (HA) offers several benefits for businesses and their websites or applications:

- Improved uptime: HA systems minimize downtime, ensuring that your website or application remains accessible to users even during server failures or maintenance.
- Enhanced user experience: By maintaining consistent performance and availability, HA systems contribute to a better user experience, helping to retain users and build customer loyalty.
- Increased reliability: HA systems provide a dependable hosting environment, giving businesses peace of mind knowing their online presence is consistently maintained.
- Scalability: HA solutions are designed to accommodate increased traffic and resource demands, allowing your website or application to grow alongside your business.
- Cost savings: By minimizing downtime and performance issues, HA systems can help prevent revenue loss and reduce the potential costs associated with website outages or disruptions.

High Availability Hosting: Boost Your Business with Unmatched Uptime

In today's digital era, having a reliable and high-performance website is critical for any business to succeed. HOSTKEY high availability hosting is the perfect solution to guarantee your website's uptime, minimize downtime, and ensure a seamless user experience. HOSTKEY offers high availability cloud hosting services that cater to all your business needs, providing a robust and efficient hosting environment.

What Is High Availability Hosting?

High Availability Hosting is a solution that ensures maximum uninterrupted operation of a website or application through hardware redundancy, automatic failover and load balancing.

Key features of high availability hosting:

minimal downtime (simple) — the system automatically switches to backup servers if the main one fails;
scalability — the ability to quickly increase resources as the load increases;
geo-distribution (geo-redundancy) — data is stored in several data centers to protect against regional failures;
automatic monitoring (auto-failover) — constant monitoring of server status and instant response to errors.

This approach guarantees uptime of 99.9% and higher, which is critical for business applications, online stores and high-load projects.

How HOSTKEY Delivers High Availability

Нo Single Point of Failure

HOSTKEY eliminates the risk of downtime due to a fully redundant infrastructure. All critical components, including servers, network connections and data storage systems, are duplicated, which guarantees uninterrupted operation even if individual elements fail.

Automatic Failover

In case of failure on the main server, the system automatically redirects traffic to backup capacities without human intervention. This minimizes downtime and ensures uninterrupted operation of services.

Load Balancing

Distributing requests across multiple servers prevents overload and increases fault tolerance. HOSTKEY uses intelligent balancing algorithms that optimize performance and response speed.

Tier III Data Centers in Europe and the USA

HOSTKEY infrastructure is located in highly reliable data centers with 99.982% uptime, backup power supply and DDoS protection. Geographical distribution reduces the risk of regional failures, ensuring global availability of services.

Benefits of Virtualized High Availability Hosting

The advantages of virtualized High Availability Hosting are as follows:

Maximum fault tolerance. A virtualized high availability hosting environment automatically migrates virtual machines to healthy servers in the event of hardware failures, minimizing downtime.
Efficient use of resources. Virtualization technologies allow dynamic distribution of computing power between servers, avoiding overloads and reducing equipment costs.
Fast scaling. You can quickly increase or decrease resources without physical intervention, which is especially important for growing projects with variable loads.
Simplified backup and recovery. Virtualization simplifies the creation of backups and speeds up data recovery after failures, providing an additional level of protection.
Flexibility and isolation of environments. Each virtual machine operates independently, which increases security and allows you to test updates without risk to the main environment.
Global availability. Hosting virtual servers in distributed data centers reduces the risk of regional disasters and improves response speed for users from different countries.
Cost reduction. Virtualization reduces hardware costs (CAPEX reduction) and allows you to pay only for the resources used, which makes high availability hosting an economically advantageous solution.
